Description
Circuito para reducir la energía almacenada en
un generador electroquirúrgico.
La presente descripción se refiere en general a
un sistema electroquirúrgico, y más concretamente, a un sistema
para descargar el exceso de energía de una corriente continua de
alta tensión (HVDC) del suministro de potencia de un generador
electroquirúrgico.
La electrocirugía implica la aplicación de una
corriente eléctrica de alta radiofrecuencia a un lugar quirúrgico
para cortar, obturar, separar o coagular tejidos. En la
electrocirugía monopolar, una fuente o electrodo activo suministra
energía de radiofrecuencia desde un generador electroquirúrgico al
tejido y un electrodo de retorno transporta la corriente de nuevo
al generador. En la electrocirugía monopolar, el electrodo fuente es
típicamente parte de un instrumento quirúrgico mantenido por el
cirujano y aplicado al tejido que ha de ser tratado. Un electrodo
de retorno de paciente está colocado remotamente del electrodo
activo para transportar la corriente de nuevo al generador.
En la electrocirugía bipolar, un instrumento
mantenido a mano transporta típicamente dos electrodos, por ejemplo,
el fórceps electroquirúrgico. Uno de los electrodos del instrumento
mantenido a mano funciona como el electrodo activo y el otro como
el electrodo de retorno. El electrodo de retorno se coloca en
estrecha proximidad con el electrodo activo (es decir, el que
suministra corriente) de modo que se forma un circuito eléctrico
entre los dos electrodos. De esta manera la corriente eléctrica
aplicada está limitada al tejido del cuerpo posicionado entre los
dos electrodos.
El documento
WO-A-9827880 describe un generador
electroquirúrgico, en el que la potencia de la frecuencia de radio
suministrada se reduce en respuesta a la tensión de salida pico que
muestra un umbral.
Los generadores electroquirúrgicos
convencionales incluyen una potencia de la corriente una corriente
continua de alta tensión (HVDC) conectada a una etapa de salida de
radiofrecuencia (RF), que convierte la energía de la corriente
continua DC generada por la HVDC en energía de RF. El suministro de
potencia de la corriente continua de alta tensión (HVDC) incluye un
filtro de salida que suaviza la conmutación de la HVDC dentro de un
nivel de DC. Este filtro puede almacenar una gran cantidad de
energía y bajo cargas ligeras y alta impedancia, la descarga del
filtro de salida es lenta. Como un resultado, el tiempo de respuesta
del generador se reduce significativamente limitando de ese modo la
capacidad del generador para impulsar energía rápidamente o
responder rápidamente durante las cargas ligeras.
Por lo tanto, existe una necesidad de un
generador quirúrgico que pueda descargar energía de una manera
consistente y rápida sometido a diversas condiciones de carga, que
incluyan cargas ligeras y alta impedancia.
Según la presente invención se describe un
generador electroquirúrgico que incluye una fuente de potencia de
alta tensión para generar corriente continua, una etapa de salida de
radiofrecuencia para convertir la corriente continua en energía de
radiofrecuencia, y un circuito para descargar energía almacenada. El
circuito incluye un modulador de anchura de los impulsos para
controlar un suministro de potencia de alta tensión, un circuito de
generación de señales de error configurado para suministrar una
señal de error como una diferencia entre una tensión de la señal de
salida con una tensión de realimentación generada por el suministro
de potencia de alta tensión. La señal de error es transmitid al
modulador de anchura de los impulsos. El circuito incluye además un
circuito de conmutación configurado para conmutar en una carga en
paralelo con una salida del suministro de potencia de alta tensión
cuando la señal de error es menor que un primer umbral
predeterminado para descargar la salida. Si la señal está por
encima de un segundo umbral el modulador de anchura de los impulsos
es conmutado conecta. Esto garantiza que el modulador de anchura de
los impulsos y de la carga no se activan simultáneamente.
Los aspectos anteriores y otras características
y ventajas de la presente descripción, serán más evidentes a la luz

Las realizaciones preferidas de la presente
descripción se describirán en esta memoria más adelante con
referencia a los dibujos que se acompañan. En la descripción
siguiente, las funciones o construcciones bien conocidas no se
describen detalladamente para evitar el obscurecimiento de la
presente descripción con detalles innecesarios.
La presente invención se proporciona para un
generador electroquirúrgico que incluya un suministro de potencia
de alta tensión para suministrar una tensión de DC, un filtro de
salida, y un circuito de descarga activo para descargar eficazmente
la energía almacenada en el filtro de salida. El circuito de
descarga activo conmuta en una carga en paralelo con el filtro de
salida de modo que la energía almacenada en el filtro de salida es
descargada de manera consistente independientemente de la
resistencia de la carga externa.
El generador según la presente descripción puede
ser usado con dispositivos electroquirúrgicos bipolares y
monopolares. La Figura 1 es una ilustración esquemática de un
sistema electroquirúrgico monopolar 1. El sistema 1 incluye un
electrodo activo 14 y un electrodo 16 de retorno para tratar el
tejido de un paciente P. La energía de RF electroquirúrgica se
suministra al electrodo activo 14 mediante un generador 10 a través
de un cable 18 que permite que el electrodo activo 14 erosione,
corte o coagule el tejido. El electrodo 16 de retorno se coloca en
el paciente P para devolver la energía desde el paciente P al
generador 10 por medio de un cable 15.
El generador 10 puede incluir controles de
entrada (por ejemplo, botones, activadores, conmutadores, etc.)
para controlar el generador 10. Los controles permiten que el
cirujano ajuste la potencia de la energía de RF, la forma de onda,
y otros parámetros para conseguir la forma de onda deseada adecuada
para una tarea particular. (por ejemplo, cortar, coagular, etc.).
Dispuesta entre el generador 10 y el electrodo activo 14 sobre el
cable 18 hay una pieza 12 de mano, que incluye una pluralidad de
controles de entrada que pueden ser redundantes con ciertos
controles de entrada del generador 10. La colocación de los
controles de entrada en la pieza 12 de mano permite la modificación
más rápida y fácil de los parámetros de energía de RF durante el
procedimiento quirúrgico sin que el cirujano tenga que desviar su
atención del lugar quirúrgico y retornar al generador 10.
La Figura 2 muestra un diagrama de bloques
esquemático del generador 10 que tiene un controlador 26, un
suministro (HVDC) 28 de potencia de la DC de alta tensión, y una
etapa 30 de salida de RF. El controlador 26 incluye un
microprocesador y un puerto de salida del microprocesador está
conectado eléctricamente a la HVDC 28. La HVDC 28 está configurada
para suministrar potencia de DC a la etapa 30 de salida de RF. El
controlador 26 recibe señales de entrada del generador 10 y/o de la
pieza 12 de mano, por ejemplo, un punto del conjunto, y el
controlador 26 a su vez ajusta la potencia emitida por el generador
10, más concretamente la HVDC 28, y/o ejecuta otras funciones de
control en la misma.
La etapa 30 de salida de RF convierte la
potencia de la DC en energía de RF y suministra la energía de RF al
electrodo activo 14. En adición, la etapa 30 de salida de RF recibe
también energía de RF del electrodo 16 de retorno. La potencia de
la HVDC 28 puede ser variada para modificar la magnitud de la RF
(por ejemplo, la amplitud) ajustando de ese modo la potencia de la
energía de RF suministrada al tejido. Esto permite la regulación
exacta de la potencia de la energía de RF suministrada.
La regulación de la energía de salida está
controlada por el controlador 26 (por ejemplo, un microprocesador)
usando algoritmos y/o software. El controlador 26 forma un bucle de
control cerrado con un sensor 29 que detecta diversos tejidos y
propiedades de la energía de salida y comunica los datos de las
propiedades al controlador 26. El bucle de control cerrado permite
el ajuste en tiempo real de la energía de salida basándose en las
propiedades detectadas por el sensor 29. Más concretamente, el bucle
de control cerrado puede procesar señales del sensor 29 y efectuar
los ajustes correspondientes en alrededor de 250 \mus. La HVDC 28
es capaz de suministrar y descargar la corriente a regímenes
similares (por ejemplo, siendo generada a alrededor de 300 V/ms o
más rápidamente y descargar a alrededor de 7 V/ms o más
rápidamente).
Con referencia a la Figura 3, la descarga de
corriente se efectúa usando un circuito (ADC) 31 de descarga activo
- un componente de la HVDC 28 - que es un circuito que conmuta una
carga 36 (por ejemplo, uno o más resistores) en paralelo con un
conductor 34 de salida. La HVDC 28 incluye un diodo 33 sobre una
conexión 35 de salida que permite que la corriente circule fuera de
la HVDC 28 dentro de un filtro 32. La carga 36 descarga la energía
almacenada en el condensador 34. Durante la descarga, el diodo 33
impide que la corriente de descarga retroceda dentro de la HVDC 28
dirigiendo de ese modo la corriente hacia el electrodo activo
14.
La Figura 4 muestra la ADC 31 con más detalle y
otros componentes del generador 10. Las conexiones 35, 37 de salida
y entrada incluyen una pluralidad de diodos 33 que bloquean la
corriente de salida impidiendo su retorno a la HVDC 28 durante la
descarga. La HVDC 28 está conectada a un modulador 38 de anchura de
los impulsos, que puede ser un Modulador de Anchura de Impulsos
UCC3895 disponible de "Texas Instruments", para controlar la
salida de la HVDC 28. El modulador 38 de anchura de impulsos ejecuta
el control de una etapa de potencia de puente entero desplazando de
fase la conmutación de medio puente con respecto al otro. Esto
permite la modulación de la anchura de los impulsos de frecuencia
constante en combinación con la conmutación de tensión cero
resonante que conmuta para proporcionar alta eficiencia a altas
frecuencias y puede ser usada como un controlador de modo de
tensión o un controlador de modo de corriente.
El modulador 38 de anchura de impulsos está
configurado para recibir una señal de error que es generada por un
circuito de generación de señales de error, un primer comparador 52.
La señal de error es deducida de la diferencia entre el punto
establecido de salida de la HVDC 28 (por ejemplo, ECON) - la tensión
de salida pretendida - y la
realimentación de la tensión de la HVDC 28 (VFB) - tensión de salida
real generada por la HVDC 28. Si VFB es más alto que ECON, sin el
ADC 31, la señal sería de 0 V. Esto origina que el bucle sea
retardado a medida que espera que la señal aumente para activar el
modulador 38 de anchura de los impulsos. El ADC 31 evita ese
problema y mantiene la señal sin que descienda demasiado bajo porque
el ADC 31 descarga la salida de la HVDC 28 con más rapidez de lo
que la señal puede caer. La señal de error es enviada al controlador
38 de desplazamiento que compara la señal de error con una segunda
señal predeterminada. Si la señal cae por debajo del segundo umbral
predeterminado, alrededor de 0,7 V, el modulador 38 de anchura de
los impulsos cierra y el ADC 31 se hace operativo. Cuando el
modulador 38 de anchura de los impulsos cierra, la HVDC detiene la
corriente de la fuente.
La señal es comparada también con un primer
umbral predeterminado, de alrededor de 0,5 V, en un segundo
comparador 50. Por tanto, si la señal es inferior a este nivel el
ADC 31 se hará conductor. Esto garantiza que el modulador 38 de
anchura de los impulsos no se hará conductor cuando el ADC 31 es
conductor reduciendo de ese modo la posibilidad de la HVDC 28
accione dentro de la ADC 31. La alimentación de la señal dentro del
segundo comparador 50 no es filtrada, esto permite una respuesta
relativamente rápida del ADC 31. El periodo de tiempo entre la
interrupción del modulador 38 de anchura de los impulsos y el inicio
del ADC 31, o viceversa, es de alrededor de
5 \mus.
5 \mus.
Como se ha expuesto anteriormente, el conductor
34 está en paralelo con la carga 36 que se usa para descargar la
corriente. La carga 36 proporciona una tensión de accionamiento de
la puerta e incluye un componente 40 de conmutación y un elemento
resistivo 42. El componente 40 de conmutación puede ser un
transistor, tal como un transistor de efecto de campo (FET), un
transistor de efecto de campo semiconductor de metal óxido (MOSFET),
un transistor bipolar de puerta aislada (IGBT), un relé, y
similares. El elemento resistivo 42 está en serie con el componente
40 de conmutación y la toma de tierra 44, siendo conocido como un
seguidor de la fuente. El seguidor de la fuente limita la cantidad
de corriente que circula a través del elemento resistivo 42. A
medida que aumenta la cantidad de corriente que circula a través del
elemento resistivo 42, la tensión a través del elemento resistivo
42 aumenta también. Esta tensión se sustrae de la tensión de
accionamiento de la puerta originando cuando alcanza un umbral
predeterminado que el componente 40 de conmutación se desconecte
actuando de este modo como un resistor variable. El elemento
resistivo 42 tiene una resistencia, tal como de alrededor de 5
ohmios, que limitará la corriente a menos de alrededor de 2
amperios. Por ejemplo, el elemento resistivo 42 tiene una
oscilación de alrededor de 2 voltios y 2 amperios y sustraerá
10V(2A*5 ohmios) de los 12 V de excitación de la puerta.
Esto reduce los esfuerzos sobre la HVDC 28 y otros componentes de
salida.
\vskip1.000000\baselineskip
Las Figuras 5A-E son gráficos de
la salida de HVDC 28. La Figura 5A muestra la respuesta de salida de
la HVDC 28 sin el ADC 31 en tanto que la Figura 5B muestra la
respuesta de salida de la HVDC 28 equipada con el ADC 31. La forma
60 de onda representa la tensión ECON (por ejemplo, la tensión de
salida pretendida) que fluctúa desde alrededor de 0,5 V a alrededor
de 1 V. La forma de onda 62 es la salida de tensión de la señal real
(por ejemplo, la realimentación de la tensión) que es una forma de
onda senoidal de 1 KHz de la HVDC 28 dentro de una carga de
alrededor de 200 ohmios. En la Figura 5A, las formas 60, 62 de onda
no tienen la misma forma, representando retardo en la descarga de
la corriente. En la Figura 5B, las formas 60, 62 de onda tienen
trayectorias más parecidas entre sí debido a la descarga más rápida
causada por el ADC 31.
Las Figuras 5C-D muestran una
forma 64 de onda que representa el accionamiento de la puerta del
componente 40 de conmutación. Cuando la forma 64 de onda de
accionamiento de la puerta muestra una elevación es representativa
del componente 40 de conmutación que está conectado activando de ese
modo una carga de 5 ohmios a través de la salida. En la Figura 5C,
los impulsos accionan la puerta abriéndola y cerrándola muy
rápidamente, de tal modo que durante la porción con pendiente
descendente de las formas de onda 60, 62 el accionamiento de la
puerta está abierto y se cierra durante la porción con pendiente
hacia arriba de las formas 60, 62 de onda. La Figura 5D muestra una
vista expandida del accionamiento de puerta que muestra el régimen
pulsatorio, que es de alrededor de 230 KHz. Esto demuestra que el
ADC 31 está manteniendo la señal evitando que caiga por debajo de
0,5 V.
Las Figuras 5E-F muestran
diferencias de tiempo entre las formas de onda 60, 62, 64. Más
concretamente, la Figura 5E muestra que el periodo de tiempo que
transcurre entre la desconexión del modulador 38 de anchura de los
impulsos y la conexión del ADC 31 es de alrededor de 4 \mus,
mientras que la Figura 5F muestra que el periodo de tiempo entre la
conexión del modulador 38 de anchura y la desconexión del ADC 31 es
también de alrededor de
15 \mus. Esto demuestra que el ADC 31 y el modulador 38 de anchura de los impulsos no se activan al mismo tiempo, lo cual reduce el riesgo de sobrecargar los componentes del generador 10.
15 \mus. Esto demuestra que el ADC 31 y el modulador 38 de anchura de los impulsos no se activan al mismo tiempo, lo cual reduce el riesgo de sobrecargar los componentes del generador 10.
